most areas that have the build up would have been cleaned/replaced with the cylinder head work.
To me, the time to do this would be in conjuction with a plug change. Its seems the mileage increment for doing it would be similar.
I did my wifes 03 Thunderbird over the weekend. It was a lot different than the 6 cylinder on my truck. It injested 1/2 a can. I let it sit for 20 minutes, then started it up and put the rest of the can in.
I asked my wife to go drive it hard 3 miles down the road, then come back.
No smoke until after she backed up, turned right out of the driveway, then mashed the gas pedal. She left an 1/8 mile trail of smoke. lol. My truck was smoking hard while at idle.
Not sure the reason for the difference. The thunderbird gets "hammered" more than the truck so there may be less carbon in there. Not sure.
